Don’t get caught winging it! Follow these tips for a safe and healthy winter.

As the temperatures get colder, make sure you know how to stay warm. Wear warm winter clothes and plenty of extra layers, and listen for radio or television reports of travel advisories issued by the National Weather Service.

Play it Safe Outdoors  

Penguin sliding on iceUnfortunately, we don’t have downy penguin coats to keep warm. When going outside, do not leave areas of the skin exposed to the cold. Learn to recognize the symptoms of hypothermia and frostbite.

When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature. Body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is happening and won’t be able to do anything about it. Victims of hypothermia are often elderly people with inadequate food, clothing, or heating, babies sleeping in cold bedrooms, and people who remain outdoors for long period.

Warnings signs of hypothermia include shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, and drowsiness. If you notice any of these signs, take the person’s temperature. If it is below 95°, the situation is an emergency—get medical attention immediately.

Driving in a Winter Wonderland

Driving in severe winter weather can be dangerous and lead to accidents. Be sure to prepare a winter emergency kit for your car.  Include blankets, a flashlight, a shovel, an ice scraper, water and snacks, and a first aid kit. Make sure your car is serviced and has a full gas tank before a storm. Consider signing up for an all-weather driving course in your area to practice winter driving skills, and know what to do if you ever become stranded in your car.

Huddling is great, but may not be enough to keep you warm when winter weather hits. Learn how to prepare your home for winter weather and save on your electricity and heating bills. Insulating walls and attics, and putting weather-strips on doors and windows keeps heat inside and maximizes warmth.

Handle Heating Equipment Safely

When you need to warm up, take proper precautions and review instructions before handling heating equipment and fires. Have your heating system serviced by a qualified technician every year. Make sure fireplaces, wood stoves, and other combustion heaters are properly vented to the outside. Never leave children unattended near a space heater. Learn more by reading CDC’s Indoor Safety Guide.

Don’t Forget Your (Other) Furry Friends

walk like a penguinIf you have pets, make sure to bring them indoors. If you cannot bring them inside, provide adequate shelter to keep them warm and make sure they have access to unfrozen water.

Stay Chill around Ice

Walking on ice is dangerous and can cause serious falls on driveways, steps, and porches. Use rock salt or sand to melt the ice on driveways and sidewalks.If walking on ice can’t be avoided, walk like a penguin! Bend your back slightly and point your feet out – this increases your center of gravity. Stay flat-footed and take small steps or even shuffle for more stability. Keep your arms out to your sides to help balance.

Support Each Other

Holding Hands PenguinsAlthough it’s best to not leave the nest when severe winter weather hits, maintain your support network by checking in with family, friends and neighbors. Your neighbors might need extra help before and after a winter storm, so check in to make sure everyone is okay and has adequate heat. Use CDC’s PSAs and Podcasts to help spread winter preparedness messages. We’re all in this together!

Happy Fins: Plesiosaurs Flapped like Penguins

London Zoo

2015-04-18 13.45.36I’ve lived in London for just over two years now, but have already visited London Zoo three times.

The zoo, founded in 1826 is in the middle of London, but in one of its rare open spaces: Regent’s Park. It’s not a very large zoo, but the zoological society of London has a second – much larger – zoo outside the city, which is where the elephants are. At the moment, the lions are also temporarily out of the city, while they’re getting an awesome new enclosure.

When I was in high school, I did a mini literature research project about zoos, and learned that they have four key functions: entertainment, research, conservation and education. Since then, whenever I visit a zoo, I look for those four roles. London Zoo, perhaps unfortunately, relies very heavily on entertainment. Its Zoo Lates programme, allowing visitors to party in the zoo after hours, has been criticised for being stressful to animals. But on the other hand, the zoo’s popularity also saved it from closing in the 1990s. As a whole, though, the Zoological Society of London, which runs both London Zoo and Whipsnade Zoo, does do a lot of work on animal research and conservation, so the superficial entertainment value of London Zoo is a bit misleading.

In the three times I’ve visited London Zoo in the past two years, I also noticed that it’s currently undergoing a lot of improvements that all create more space or better enclosures for animals. Yay! The most recent one is the new lemur exhibit. It’s not as great a space as the Apenheul or Duke Lemur Center lemurs have, but much better than the old lemur cage (which you can briefly see in the 2013 video at the bottom of this post).

As part of the launch of the new lemur exhibit, the zoo’s website also has a lemur game, where you can let a lemur jump from tree to tree. (Unless you are as bad at platform games as I am, in which case the lemur just does one jump and falls to the ground. I’ll leave the jumping to real lemurs.)

Lest we turn this into the Lemur & Pea blog, let’s move on to this anteater.

This little guy was new to the tropical rainforest exhibit when I visited, and was just as curious as the visitors were. He has free reign of both the animal and people parts of the exhibits, but was still learning to deal with crowds and had two human babysitters (anteatersitters?) with him.

2015-04-18 15.23.44

We also visited the penguins, and the exhibit about penguin research. This group of penguins was recently featured in The New Yorker, in an article by Ed Yong, discussing their wobbly walk. Just another example of the “research” function of zoos!

2015-04-18 15.19.10

Even with a relatively small zoo as London Zoo, I still have never managed to visit ALL animals in one day. I’ll be back next year to visit the new lion enclosure, and here’s a video from my visit two years ago:

Warming in Our Winter Wonderland: The Role of Ice in Penguin, Polar Bear, and Ivory Gull Survival

Leopard Seal

I love to watch animal documentaries on TV. I even own Planet Earth on HD-DVD (I know, I know, serious technology miscalculation there). One of the most beautiful animals I’ve seen documented is the leopard seal. Leopard seals are named for their spotted pelts and can grow to be as large as polar bears. They are thought to be brutal and ruthless killers of penguins, fish and sometimes humans. I recently saw a TED talk by an arctic wildlife photographer (Paul Nicklen) who ran into some leopard seals while shooting penguins. Turns out these seals aren’t always bent on “kill and destroy”. The seal tried to entice him by delivering a freshly killed penguin to him and tried to feed it to his camera.

While these seals primarily live on larger game, it turns out they are capable of feeding themselves in another way. In Polar Biology, it was reported that these seals can sieve krill out of the water just like whales can. Their teeth are structured in such a way that it’s possible for them to gulp up a cloud of krill and expel the extra water keeping the krill to swallow. While this behavior hasn’t yet been documented in the wild, there’s a possibility that these ultimate predators can snack on teeny tiny krill. Turns out, they are indiscriminate binge-eaters at just about every level of the food-chain!
